SNAP-FASTENER.

To all whom it may concern:

Be it known that I, FRED A. NEIDER, a citizen of the United States of America, and resident of Augusta, in the county of Bracken and State of Kentucky, have invented a new and useful Improvement in Snap-Fasteners, of which thefollowing is a a different character to efi'e'ct its unfastening.

A further object is to produce a snap fastener adapted to be manufactured from sheet metal and not requiring the'use of any expensive metal drawing dies.

These and other objects are attained in.

the snap fastener described in the following specification and illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of a fastener embodying my invention.

Fig. 2 isan enlarged sectional view of the fastener embodying my invention taken on the line 22 of Fig. 1.

Fig. 3 is a sectional view taken upon the line 33 of Fig. 2 and upon a reduced scale.

Fig. 4 is a composite perspective view of the elements of the socket of my improved fastener.

Fig. 5 is a front elevation of the preferred I form'of my improved fastener.

Fig. 6 is an enlarged sectional view taken on the line 66 of Fig. 5.

Fig. 7 is a sectional view taken on the line 77 of Fig. 6 and upon a reduced scale.

The preferred formof my improved fastener illustrated in Figs. 5 to 7 inclusive consists of a socket 8 adapted to be mounted upon the stud 9. Socket 8 is attached, in the case of a vehicle curtain which is illustrated in thedrawings as an example, to the cure tain cloth 10. The stud 9 with which socket B cooperates i's' secured to some relatively stationaryportio'n of the vehicle body. Stud 9 referably consists of a screw threaded mem- Ber such as illustrated in Figs. 2 and 6,

Application filed April 30, 1917. Serial No. 165,353.

although the socket of my improved fastener is adapted to-gripthe walls of a smooth stud efliciently. The socket of my improved fastener, illustrated in the preferred form disclosed in Figs. 5 and 6, consists of a clip 12 having an aperture centrally located therein and having a series of sprin fingers 13 extending therefrom. Locate in the aperture of clip 12 is an eyelet 14, the upper end of which is flanged to retain clip 12 thereon,- and the inner end of which is flanged to retain a pronged plate 15 thereon. Either clip 12 or plate 15 or both are rotatively mounted upon eyelet 14 so that they may rotate relatively to one another. Prongs 16 of plate 15 are adapted to pass through the curtain material 10 and through slots 17 in a backing disk 18 which is placed against the back of the curtain material to reinforce it. This disk is provided with a centrally located aperture 19 which registers with. the

aperture of eyelet 14 so as to permit passage therethrough of stud 9. The disk is held in position upon the curtain by having the prongs 16 of plate 15 bent into engagement therewith as disclosed in Figs. 6 and 7. Clip 12 is formed ofa square sheetof metal by having the corners of thesheet turned over to positions such that their edges cooperate and lie upon the central or body portion of the sheet. The corners 20 .of the folded member thus formed are then turned up as disclosed in Figs. 5- and 6 to form lugs for engagement with the operators fingers so that clip 12 may be rotated with relation to the plate 15.. The points of the corners originally turned over to form springfingers '13, are then cut ofi to leave an opening between the lugs materially smaller than the diameter of stud 9. After eyelet 14 has been formed to retain plate 15 and clip 12 in r0 tative connection with one another, and after the socket has been secured to the curtain 10 'as previously described, it may be secured to the stud by pressing it upon the stud until fingers 13 spring to the positions disclosed in Fig. 6, in which positions they grip the screw threads of the stud and prevent removal of the socket in the same manner in which it was placed thereon. In order to remove the socket it isthen necessary to screw threads until the' fingers 13 have become disengaged from the end of the stud, at which time the curtain is unfas'tened and ready for removal.

The modified form of my improved snap fastener and which is illustrated in Figs. 1 to 4 inclusive, consists of a socket 21 adapted to be mounted upon a screw threaded stud the space between the ends is materially less than the'diameter of the aperture and ofthe stud, so that when the socket is passedover the stud, ends 24 may act as spring fingers to retain the socket in position in the same manner that fingers 13 of m preferred form retain the socket 8 in position on stud 5 9. Back of clip 23 a plate 26 is located, this v sary to displace it.

plate having prongs 27 like prongs 16 of plate 15, which are adapted to be passed through the curtain material 28 and through slots 29 in a reinforcing disk 30 located against the back of the curtain material. To secure plate 26 upon clip 23 the inner edge of aperture 25 is flanged and turned over the inner edge of an aperture formed in plate 26 so that clip 23 is rotatively mounted with relation to plate 26. Thus when the socket 21 of the-modified form of my improved construction is passed over stud 22, spring fingers 24 engage the screw threads of the stud and grip them to prevent displacement of the socket. T 0 remove the socket it is necessary to rotate clip 23 in order to disengage its fingers 24 from the end of the screw threads of the stud.

In the illustrated embodiment of my in vention I have shown sockets having but 'two and four spring fingers, but it would not be a departure from the spirit and scope 'of my' invention to vary the number of fingers.

My improved snap fastener is adapted to be used in the fastening of gloves, dresses and the like, but it is particularly adapted for use in fastening vehicle curtains for the reason that it is qulck in its application and positively holds the curtain against displacement even though in ones haste the spring fingers have been brought into engagement with but one screw thread of the stud. In

cases oi sudden storms the wind could not possibly displace the socket from the stud since an entirely different movement from that given the socket by the wind is neces- Mv improved fastener when used upon gloves andclothing will prevent dlwngage' masses ment of the fastener elements through any accidental catching of the garment or other. strains brought to bear upon it, it being necessary to unscrew the socket from the stud before the fastener could'be released.

' In its use for gloves and other garments the fastener construction would be modified materially to avoid the catching thereof in its spring fingers and other portions.

Having thus described my invention, what I claim is; 1

1. A snap fastener consisting of a stud and a socket adapted to receive the stud,

said stud having screw threads formed thereon, said socket consisting of a'plate having an aperture therein adapted toreceive the stud and a series of springs extending from the edges of the plate toward the aperture and having their endsspaced apart a dis-' tance less than the diameter of the stud, andgagement of the springs with the screw threads will prevent removal of the socket.

from the stud except by rotation thereof to disengage its springs from the screw threads.

2. A snap. fastener consisting of a socket and a stud adapted to receive the socket, said socket consisting of a plate having an aperture formed therein adapted to receive the stud, springs located on the plate and hav ing their stud engaging ends extending toward one another and adapted to yield to permit passage of. the plate over the stud when moved in one I direction and to grip the stud in the opposite direction, and'means adapted to mount the plate rotatively upon the article to be fastened, whereby the socket must be rotated to disengage the springs from the stud.

3. A snap fastener; consisting of asocket and a-stud, said socket'consisting of a plate having a centrally located aperture adapted to receive the stud and having its edges bent toward one another to provide a series of springs adapted to engage the stud when the plate is moved in one direction over the stud and to prevent removal of theplate fromthe stud in the opposite direction, and

upon the article to be fastened, whereby said plate will have to be rotated to disengage its springs from the stud.

4. A snap fastener consisting of a socket and a stud, said'socket consisting of a plate rotatively mounted upon the article to be .fastened and having an aperture adapted to receive the stud, the corners of the plate being bent toward one another to form springs and to bring their ends into posimeans adapted to mount, the plate rotatively.

tion over the aperture of the plate, whereby nae corners are formed at the points of bending between the springs and ihe remainder of ltheiplatwsaid see ond mentioned corners being adapted to be bent to form lugs whereby 5 the plate may be rotated, said springs be:'
